DPHY TX lane disable

Jump to solution

Hello,

We configured the mipi DPHY tx ip with 4 lanes.

In some configuration we need to use only one lane in HS mode.

When all the lanes are active everything is OK, but when some of the lanes are disabled the "ready" signal is never asserted again

after the first packet.

Is this behavior expected?

Thanks,

Marco

Hello Marco @marcoventurini 

Did you enable "Active lanes support" in the GUI ?

Did you set "active_lanes_in" when output is in LP-11 state ?

Thanks & regards

Thanks for your support.
